Hi!

Thanks for the report! I cannot reproduce in my system (Arch Linux + conda), so we'll try to guess what is happening here. For some reason the executable script cannot locate the pychimera package, so it might be a misconfigured environment.

I would need:

• Which OS you are using. cat /etc/issue is enough.
• The result of env | sort in your system. I am particularly concerned with $PATH and $PYTHONPATH variables.
• The result of pip --version.

Also, you might be able to use python -m pychimera instead of pychimera, but we should resolve the other issue first.

Thanks, Jaime.

PYTHONPATH is empty. Should it be set to something?

Ok, I think I have a fresh Ubuntu VM somewhere, so I will try to reproduce the error there. I think this might be related to the pip hacks Ubuntu uses for user installations. The environment variables look OK. Did you manage to run python -m pychimera? Also, it would be very useful if you could run this Python call:

python -c "import pychimera, sys; sys.stdout.write(str(pychimera.__path__)+'\n')"

I'll keep you up to date.

I have managed to reproduce your error: pychimera works, but pychimera --gui does not. A fix should be available soon... I hope :)

[jaimergp]

Ok, I think this will fix it.

Tests are passing in my local installation; let's see how it goes at Travis.

Please let me know if it works for you. You will have to install it from source like this:

pip uninstall pychimera
pip install https://github.com/insilichem/pychimera/archive/master.zip

Thanks a lot, amazing time to a working fix and excellent user support. Now, pychimera --gui works!

[jaimergp]

Glad you got it working! I will cut a new release (v0.2.7, I think) after confirming this also works in other systems.

Thanks again for the report and patience to test it!
